Cheap-o way to monitor adc values in picaxe

Fellow members,

Does any of you know of, or use a way to monitor the ADC values produced by a Picaxe analog input pin in real time?

As far as I know, the only two ways to monitor these values as they happen are: 1) with an LCD in the circuit or 2) on the programming PC via the download cable.

I was wondering f there was a cheap-o version, something you could breadboard easily and with discrete components... Ideas anyone? Or am I looking for the holy grail?

Thanks, all!



Do you need to see the numbers or

is an audio/visual indication enough? If audio or visual is enough then, pwm output to a LED, an amp and a speaker or a piezo buzzer. I am taking a page from I believe Frist’s book here.
